如何在Python中获得完整的异常？

Question

我正在用Python制作Minecraft经典服务器。但是，我的代码中出现以下错误：

Unhandled exception in thread started by <bound method Heartbeat.start of <__main__.Heartbeat object at 0x01FC3810>>

这是我的心跳代码：

^{pr2}$

我如何得到完整的回溯？在

Answer 1

您可以使用traceback模块，将您的start()方法重命名为_start()，并将此方法改为：

import traceback

[...]

def start(self, *largs):
    try:
        self._start(*largs)
    except Exception, err:
        exc_type, exc_value, exc_tb = sys.exc_info()
        traceback.print_exception(exc_type, exc_value, exc_tb)

Answer 2

用try/except包装代码

import traceback
import sys

try:
    a = 1 /0


except Exception, inst:
    exc_traceback = sys.exc_info()[2]
    print str(inst) + "\n" + str(traceback.format_tb(exc_traceback)).replace('\\n', '\n')
